drums. The lower runs of the chains pass about vertically adjustableidlers 17 mounted below the wax receptacle so as to enable thetransverse space between the chains to be maintained somewhat closewithout interfering with thercce-ptacle and so as to enable the chainsbeing kept at a proper tension.

Supported and projecting above the table between the shaft l2 and thedrums and straddling the chains -is a hopper 18 for a stack of` slats'19. The slats are set Vin the hopper so that their width extendslongitudinally of the table and chains and their length transverselythereof. The spacing of the chains is of course less than the length ofthe slats so that the slats will ride on both chains.

Fixed on the oposite shaft 1l centrally between the sprockets thereon isa spider 2O from which flexible radial arms 2l project outwardly, thesearms being preferably made of fairly stiff leather or the like. Thelength of the arms is considerably greater than the lradius of thesprocket wheels so that they will project thereabove, the table having acentralslot 22 cut therethrough to permit of the free passage of thearms. Horizontal and transversely spaced bars 23, to support the slatsafter leaving the chains, are mounted on and project beyond the table atthe spider end thereof, the top ofthe bars being the same level as thetop of the chains.

A flat presser bar 24 is mounted over the chains and drums intermediatethe hopper and spider to engage the slats carried by the chains, saidbar terminating some distance ahead of the spider. Rods 25 are securedto and project upwardly from the bar, and are slidable through brackets26 mounted on the table. Springs 27 about the rods between the bracketsand bar tend to force the bar downwardly, the movement of the bar beinglimited by nuts 28 on the rods above the brackets.

The chains are driven at any predetermined speed in a suitable mannersuch as by a belt drive 29 applied to one of the sprocket wheel shafts.The drum shaft 4 is driven at a speed somewhat less than that of thechains by aY chain ydrive 30 or the like from one of the sprocketshafts.

In operation with the driving of the chains so that the upper runsthereof travel from the hopper toward the spider the chain lugs willsuccessively engage .the lowermost slats in the hopper and will carrythem out of said hopper and past the drums. The slats coming in contactwith the revolving drums whose peripheral surfaces are Constantlyengaged with the melted wax, some of such wax will of course belimparted to the Linder surface lof the slats, :the necessary. -pressureof the slats with the drum being had by rea son ,of the presser bar.Just as .each slot after passing Tthe drums leaves the presser baritself engaged on its under surface by one of the rotating spider arms,it acts to raise said slat from a horizontal to a vertical position andthen push it a certain distance horizontally, and, while it is standingon edge, onto the bars 23 and against the slat ahead, and of coursealready vertically disposed, as shown. The armsbeing flexible they canyield when moving downwardly and clear of the slat after the latter hasbeen moved into stacked relation with the ones beyond, while at-the same-time `having sufficient rigidity to readily raise the light slats fromtheir horizontal positions on the chains. The spider arms are setrelative to the chain lugs which engage and move the slats forward, soAthat they are in position to Yengage each slat as it is advanced by the,chains in continuous and synchronized relation with the movement of thechains and slats.

The raising and stacking of theslats causes the waxed face of one slatto be abutted against the unwaxed face of an adjacent slat in the stack,as will be evident, so thatsome of the wax will adhere to the previouslyunwaxed face, and will cause a quick andeven permeation or penetrationof the wax throughout the entire body of the-slats to be had when theyare subsequently treated. This stacking also makes it easy for theworkers to gather up a batch at a time from theL supporting bars, aswill fbe evident. By the USG Of SGVl'al IlLIIOWV dl'lllllS lllSteELd0160116 Vwide one the wax is more widely distributed over the area ofthe slatsthan would otherwise be the case, and with the use of a minimumamount of wax. This alsoaids incansing the wax .to more readily permeatethe entire area of the slats.

From the foregoing description it will be readily seen that we haveproduced such a device as substantially fulfills the objects of theinvention as set forth herein.

l/Vhile thisspeciiication sets forth in detail the present and preferredconstruction of the device,- still in practice such deviations therefrommay be resorted to as do not form a departure from the spirit of theinvention, as defined by the appended claims. l
